Yea renewed at the end of last Jan. If I paid in Jan then it should last until the end of Jan right, since you pay for the current month also? O_o
Maybe I'll use the SORN trick to let it tick over and then re-tax it. Like when changing owner.
You don't need to SORN a car to get a full 12 months tax on renewal. Either you've mis-remembered when you taxed it last year or something has gone wrong, it's not normally the case that you 'lose' a month.
